?? Advancing Noise Measurement Technology! ?? At the recent InterNoise conference in France, Erik Aflalo presented an advanced 3D sound intensity probe, a new technology poised to make a substantial impact on environmental noise monitoring. Key highlights: ?? Objective: Enrich sound pressure measurements with precise directionality (azimuth & elevation) for unattended noise events. ??? Challenges: Developing a compact, weatherproof sensor that's easy to deploy and operates effectively in various field conditions. ?? Solution: A 3D intensity probe with 8 microphones, offering reliable performance from 125 Hz to 4 kHz, ensuring accurate results even in outdoor settings. This development represents a significant advancement in the field of environmental noise assessment, offering a more efficient and precise tool for monitoring. #NoiseMeasurement #Innovation #Acoustics #InterNoise2024 #NTiAudio

The active control of sound is based on the fundamental physical principle . ?? The fundamental basis for active sound control techniques is based on the superposition principle, which is a fundamental property of linear systems, that states that when two or more waves travel through the same space simultaneously, the net response is the sum of the individual waves ???? . This article, written by Jordan Cheer and Flix Langfeldt, provides a ?? brief tutorial on the physical basis of active sound control ?? review of its historical development ?? and provides possible future potential of active sound control .

Sound Bite: What was the idea behind the unique construction of Stonehenge? ?? . A research by Trevor Cox has shed light on Stonehenge's intriguing acoustic properties . Cox found that the stones amplified voices by four decibels, significantly improving speech intelligibility within the circle. In a natural environment like the grassy hill where Stonehenge stands, a speaker facing away from a listener would only be understood about one-third of the time. However, the stone reflections at Stonehenge allowed 100% of sentences to be understood. This suggests that those inside the stone circle could communicate clearly, while those outside were likely excluded from hearing any ceremonies. .

??Exciting News: We're thrilled to announce that the XL3 Acoustic Analyzer now supports speech intelligibility measurements according to IEC60268-16 ?? . ?? Measurement Flexibility ?? Background Noise Handling ?? Averaging ??Comprehensive Reporting . What is STIPA? STIPA (Speech Transmission Index for Public Address Systems) measurements are carried out to evaluate the speech intelligibility of public address systems in different environments. Typically, STIPA measurements are performed in conference rooms and classrooms, on public transport announcement systems, at theatres, sports stadiums, hospitals and many more. If a public address system is designed for safety-related emergency announcements, the minimum requirement for STIPA values must be demonstrated by measurement and documentation. . read more about it ?? https://lnkd.in/ef3Y_FR4 . . #NTiAudio #AcousticAnalysis #STIPA #SpeechIntelligibility #XL3

Do you know what the Schumann resonance is? ?? . Lightning ? and other natural processes in the atmosphere, including space weather ??, generate electromagnetic waves, also known as Sferics, which travel around the earth between the earth's surface and the Ionosphere ?????? . -If this radiation has the right wavelength, it is amplified and superimposed. This creates standing waves that travel around the earth about eight times per second . The fundamental frequency is 7.83 Hz. ?.
